A neuropathologist should then review the tumor tissue. The WHO classification scheme recognizes 15 variations of meningiomas according to their cell type as seen under a microscope. Patients with NF2 are more likely to develop meningiomas because they have inherited a gene that has the potential to cause normal cells to become cancerous.

For malignant meningioma, the 5-year survival rate is over 66%. The concept of frailty has emerged as a tool helping to gauge overall health status and risk of adverse events in aging patients, has shown to exhibit a linear relationship with poor survival in the elderly.

What websites do you recommend? Intraventricular meningiomas, which grow within the ventricles of your brain. It may also be given for small tumors as an alternative to surgery.
